title = "The effect of underlying bone on the beam angular correction in calculating the skin dose of the head in neuro-interventional imaging",
abstract = "EGSnrc Monte-Carlo software was used to calculate the {"}patient's skin dose{"}as a function of incident beam angle for cylindrical water phantoms with underlying subcutaneous fat and various thicknesses of bone. Simulations were done for incident angles from 90 to 10 degrees, entrance beam sizes from 5 to 15 cm, and energies from 60 to 120 kVp. The depth-averaged scatter-plus-primary to incident-primary dose ratio decreases with decreasing skin incident angle and increasing underlying bone thickness, and increases with increasing field size and energy. Corrections for these factors improve the accuracy of skin-dose estimation for neuro-interventional procedures with our Dose-Tracking-System.",
